Time to try manual fan control. Set /sys/class/hwmon/hwmon1/device/temp[1-5]_auto_channels_pwm to 0, then set pwm[1-8] directly to some value and see if it affects the fnn speed. My concern right now is that temp6 (which does not seem to be enabled in your system) may be configured to control all fans. If it is not connected, it may report a super-high temperature, which in turn would result in the high fan speeds. If the above does not work, this may be the case. If so, you may have to try a patched driver. Is this possible ?
